invention relates to means whereby the retaining valves of the air lines of a railroad carmay be properlyanchored orsecured to' the end walls of railroad-cars; said means involving a construction which permits of.ver-

'tic'al adjustment to be "made in'the event of replacement or renewal of the vertical portion of the air line or pipe; while at the same time permitting adjustments to compensate for any possible variations that may occur in the relation between the bolt-holes in the laterally disposed lug of the retaining'valve.

The invention contemplates means whereby the retaining valve will' be firmlysecured to the wall of the car, while at the same timepermitting adj ustlnent and detachment of the valve withoutnecessitating removal .of the supporting means or anchorand therefore without necessitating entering into the car which, at frequent .times,would' require the lading ofthe car to be removed.

The objects and advantages of our invention willbe readily comprehended fromlthe detailed description of "the accompanying drawing,- wherein i Figure 1 is a front elevation of a retaining valve attached to our improved retaining valve anchor which is shown attached to a portion of a car wall and with a portion of the air pipe secured to the valve.

Figure 2 is a side elevation of the structure disclosed in Figure 1, with a portion of the car wall shown in section.

I Figure 3 is a perspective view of our improved retaining valve anchor.

In the exemplification of the invention as disclosed in the accompanying drawing, 10 indicates a portion of a car wall, usually the end wall adjacent to which a portion of the air line or pipe is vertically disposed; a portion of the pipe being shown at 11.

Attached to the upper end of the vertical pipe 11 is the usual well known type of retaining valve 12. These valves are generally provided with laterally disposed lobes or ears 13, 13 provided with bolt-holes for the reception of suitable bolts whereby the retaining valve is fastened in place. As the valve is of well known construction and formsno part 11 At the same tune.

of our invention, a detailed. description there'- Our improved: means involves a suitable I plate 14, preferably rectangular as shown in Figure 3, provided at aisuitable point with a number of 'bolt or rivet-receiving. holes, as at 15, 1 5. In the particular exemplification,

the plate 14 is shown riveted at- 16 to the car walllO, although it is obvious that where the car' wall is of wood construction, suitable bolts may be employed if desired insteadof rivets. a a

I The lateral width of the plate ,14 is: preferably somewhat greater than thedistance between the ends of the lobes 13,123 of the retaining valve; and the plate, at points commensurate with the usualdistance between the centers of the-bolt-holes in the. lobes or ears 18, 13 is'providedwith a. pair of projec 'tions orpins 17, 17 arranged parallel with each other and extending outwardly fromthfe rectangularly formed base portions 18. The opposite sides of'the base portions1-8 are each provided with a pivot-providing pin or provjecti0n19,see Figure 2. Thepins'19 are olfset from the center or median line of the pins '17 and are formed integral with or secured to the base portions 1 8 so as tobe immovable so far as the portions;18are-concerned; while the outer ends of said .pins 19- are preferably flared or provided withthehead portions 20 which are'countersunk in the rear; face of the plate 14:- Thepl-ate l lis provided with openings throughwhich the pins 19 are disposed, with'the head'portions 20 of the-pins so arranged that tight frictional relation with the plate 14 will; be provided andthe too free rotaryimovement-of the pins 19 in the platelprevented;

the (if the pins 19 in theplate l lis such that rotation of-the pins ,19 by the use of sutficient force through the application of .a suitable tool "orwrench to the squared-or angularly faced portion 18 is possible andthe portions 18 moved aboutthe. axes of the;pins.1,9, 1 9.

It is apparent from the construction shown that i by causing the composite valve holding pins -17+18-.19tobe moved .abouttheir axes,

vthe centers 17,517 l'm ay be" moved in the event replacement of the retaining valve is necessary and a variation in the distance between the bolt-holes of the new retaining valve is encountered, our improved anchoring means may be easily adjusted to compensate for such variation by simply 'rotating the anchoring means about the axesv of the pins 19, 19 to a suflicient extent thereby causing the valve-lug receiving portions; or pins 17, 17 to be moved farther apart or brought closer together, as the case may be; such movement being due to the eccentric relation of the pins 19, 19 to the pins 17, 17.

It is thus clearly'apparent that our improved anchor is readily adaptable to retaining valves wherein the distance between the centers of theholes in the valve-lugs may slightly vary.

The pins or projections 17, 17 are of length sufficient to extend through the valve-lugs and are preferably threaded as shown at 21, to receive suitable nuts 22, after the valve is in place, for the purposeof firmly holding the retaining valve in place on the anchor.

The valve receiving projections or pinspreferably are shown with the squared or angular portions or'bases 18, which permit a wrench to be readily applied when it is found necessary to adjust the relation between the "pins 17, 17; thebases 18 at the same time maintaining proper spaced relation between the valve 12 and the plate 14.

It is evident that the degree of adjustment is con-trolled by theextent to which the portions 19, 19 are off-set from the axial centers of the portions or pins 17, 17; and that the manner of construction of said pins and their attachment to the base plate 14 may be altered without, however, departing from the spirit of our invention.

In the event of vertical adjustment being necessary by reason of variation in length of the air pipe, such adjustment may be had by rotating the pins so as to cause pins17, 17 to be disposed above orbelow the axial centers of the pins 19, 19.

What we claim is pair of valve receiving pins off-set intermediate of their ends, with one end of each pin rotatably secured in the supporting plate.

A retaining valve anchor comprising a supporting plate adapted to be secured to a car-wall, said plate being provided with valve enga'ging means rotatably secured thereto, with said secured portions of the means off-set from the longitudinal axes of the valve receiving portions to permit vertical adjustment of the valve receiving portions and to accommodate varying bolt-hole relationsupon rotative movement of said means, said means having wrench receiving andvalve spacing portions. 7
